Example

If the highest data rate of any user channel connected to a /SDM module is

9.6 kbps, and you have to transfer two 9.6 kbps channels, then Table 1-5

shows that you can also transfer three 4.8 kbps channels, or two 4.8 kbps

channels and one 2.4 kbps channel, or one 4.8 kbps and two 2.4 kbps

channels, or three 2.4 kbps channels.

Note that you can always use less channels than the maximum specified by

the table.
